The dual guitar attack, the glass shattering vocals, the heavy beats -- they're the kind of things you've come to love and expect from Judas Priest over the years, but not exactly what you would expect to be at the top of the list to put your kids to sleep.

However, the folks at Twinkle Twinkle Little Rock Star continue to show the mastery of some of metal's most hard hitting melodies by transforming the classics into lullabies for children.

Your kids may no longer be crying after midnight once you put on Twinkle Twinkle Little Rock Star's rendition of 'Living After Midnight' (which can be heard above). And if they think they can ward off the sandman, these toddlers have another thing comin'.

The set includes six Judas Priest classics getting the lullaby treatment -- the aforementioned 'Living After Midnight,' plus 'Breaking the Law,' 'You've Got Another Thing Comin',' 'Electric Eye,' 'Turbo Lover' and 'Painkiller.' Might as well start sewing the seeds of the next metal generation early by turning your infants on to the lullaby versions of Judas Priest classics.
